'To all whom t 'may concern:

Be it known that l, HERBERT E. Cooney, a citizen of the United States, residing at l/Vest Bend, county of lilashington, and State of l/Visconsin, have invented new and useful improvements in Nailing and Tacking Machines, of which the following is a specication.

My invention relates to machines for automatically tacking or nailing the laps of bent packages, such for example as cheese boxes, half-bushel measures, and in fact all kinds of receptacles formed of veneer.

My invention is further explained by reference to the accompanying drawings, in which- Figure 1 is an end view.

Fig. 2 is a side elevation.

Fig. 3 is a section on line 3 8 of Fig. 1.

Fig. 4 is a fragmental end view of the machine adjacent to the drum, parts being broken away.

Fig. 5 is a section on line 5 5 of Fig. 3.

Fig. 6 is a perspective View of the receptacle removed from the machine.

Fig. 7 is a section on line 7 7 of Fit Fig. 8 is a section on line 8 8 of Fi Fig. 9 is a section on line 9 9 of F1 Fig. 10 is a modified form, on line 10-10 of Fig. 11, and

Fig. .11 is also a modified form of veneer feeding bracket.

Like parts are referred to by the same reference numerals throughout the several views.

1 is the receptacle which is made with my machine. 2 is a hopper or box in which nails or tacks 3 are located preparatory to being driven. rlhe nails or tacks 3 fall into the open slot 4, when they are suspended by their heads 5, while they slide under the the vwheel 6 until they reach the automatic controlled feed 7. The feed 7 consists of two pointed rods 6', 6,which move across the path of the nails or tacks, and `just under the heads of the latter, thus holding said nails or tacks', and allowing the same to` slide down about one-half of an inch at a time, passing into an opening 7 in the side of the pipe 8, the nails or tacks being guided vone at a time under the punch 9 into the 'split jaw holder or guide 10.

All of the device thus far described is supported on the sliding bar 11, which bar is automatically moved about one .inch at a time, thus driving the tacks or nails into the sheets of Veneer about one inch apart, along the lap or bend of such material. The package thus formed is bent around an expanding drum 11 by hand with a telescoping crank handle 12. rlhe telescoping crank handle is adapted to be extended or contracted so as to change the leverage, as may be required. The same lever is also used to expand said drum, said drum being mounted upon the shaft 12. 13 is an electric motor which may be used for driving my machine, and when used it is connected with such machine through the belt 14 and pulley 15. The pulley 15 is mounted upon the shaft 16. 17 is a sprocket wheel which is also mounted upon said shaft 16. Motion is communicated from the sprocket wheel 17 to the two sprocket wheels 18 and 19 through the sprocket chain 20. The sprocket wheel 18 is loosely mounted on the shaft 21, said shaft being revolubly supported by the bracket 23 of the member 11. rEhe chain 2O passes loosely over all of said sprocket wheels. Motion is communicated from the sprocket wheel 18 to the nail or tack agitator wheel 6, through the pulley 22, formed on the sprocket 18, belt 24, pulley 25 and shaft 26, whereby such nails or tacks are caused to enter said slot 4, as shown in Fig. 3. The wheel 6 is provided with an annular series of grooves or depressions 27, which contact with such nails or tacks, and causes them to be agitated until they enter said slot 4. 28 is a notched bar, and said bar is fixed and causes the pawl 29, and the parts connected therewith, to move rearwardly one or more notches at a time by the action of `the lever 30, to which said pawl is pivoted on bolt 31.

Thus it is obvious that when the bar 11 has reached the position shown 1n Fig. 2

all of the nails or tacks will have beendriven. 32 is a handle by which the bar 11 and the tacking mechanism is pushed forward manually on the clamping bar 33` preparatory to tacking or nailing `the package. The clamping bar 33 is pivoted on the bolt 34, and said bolt is adjustably mounted on the frame 35. When a larger drum 11 is used the clamping bar 33 is raised by first loosening the nut 36, when the screw 37 is turned down slightly, when the nut 36 is again tightened. Thel handle32 is also used to control the movement .of `the bar 11. 38 is vibration or" the hopper 2 ythe slot 4.

a hook connected with the handle 32 by the rod 39, said hook 38 being adapted to engage the arm 40 of `the clutch pin 41, and throw such clutch pin 41 out ot engagement with any one of the notches 4:2 iormed in the hub of the sprocket 18, against the tension oi' the spring 4l. Sheets of veneer are fed to the machine on the arms 43, 43, which arms are supported by the braclret 44. The bracket 44 is also provided with lugs 45 for lining` up the veneer sheets as they are being ted into the forming device or drum 11. The expansion oi the drum l1 causestlie jaw 46 to gripone end ci t" e' veneer which is then rolled around the forming drum 11.

The lever 30 is pivotally mounted on the sliding bar 11 by the bolt 55, and saidy lever is oscillated thereon by the crank 56', xed on the shaft 21. The forward end oi'- the lever 30 engages the hammer bolt 9, as shown in Fig. 3, whereby such hammer bolt is actuated in lriving a tack or nail. f

The lever 30 is provided with an upwardly extending arm 5'?, wh`ch engages the lever 58, and causes the same to oscillate on the pivotal belt 59 for actuating the tack or nail feed mechanism 7. l

The crank 56 is locked in its downward position when the machine is at rest by the spring pressed projection 60, engaging in the notch 61 in said crank 56.

The free end of the veneer is lapped over the gripped end, and held against such gripped end by the bar 33 preparatory to being nailed as shown in Fig. 4. The bar 33 is operated by the foot pedal 47, Aby a downward pressure olf a perso'ns toot thereon, said pedal beingl connected with said bar 33 by the rod 48, connecting` loop 49 and strap 50. Said pedal is pivotally connected with the trame 35 oit the machine by pivotal bolt 51. By the Vmodiiied form shown in Figs. 410 andll, the arms 43 are provided with pins 52, which are used to guide several strips of veneer, which strips arefed into the machine at one time, said pins being used to space and line up suoli strips.v

The clamping bar 33 is provided with a notched l ar 54 iror the same purpose as said pins 52. The bar 33is raised, from clamp ing position by the spring 62, the tension of which `can be adjusted bythe screw 63v The intermittent rearward movement and feeds the tacks to In adivisional application filed by me on September 12, 1921', Serial No. 499,950,
